Hierarchical Information-Centric Networking Framework

摘要

In information-centric networking, one content publishing operation involves a great number of content routers, and different name prefixes pollute forwarding tables and result in explosion of forwarding entries. Moreover, flooding is employed to achieve information-centric communications, and this flooding incurs huge costs. Taking these issues into account, this paper proposes a hierarchical information-centric networking framework and aims to reduce the content communication costs and latency. This framework proposes the hierarchical information-centric networking architecture and name structure to achieve forwarding aggregation and avoid forwarding table pollution. This framework is evaluated, and the data show that it reduces the content communication cost and latency by nearly 49.2% and 9.5%, respectively.
